制备方法与用途

Bromine Fluoride 制备 制法

[ \text{Br}_2 + \text{F}_2 = 2\text{BrF} ]

将溴溶解于氯三氟甲烷 (CFCl₃) 中,形成悬浮液,并冷却至-75℃。然后通入稀释的氟气(以氮气为载体,浓度约为10%)。几乎定量生成一氟化溴。该物质可作为溴化试剂,在原位发生反应。

  • Bromine Monofluoride
    作者:Thomas Drews、Konrad Seppelt
    DOI:10.1002/zaac.201200293
    日期:2012.10
    BrF can be prepared by reaction of Br2 and F2 in various solvents below –100 °C. In solution it is identified by 19F NMR and Raman spectroscopy. From CH3Cl solution a single crystal structure determination of a BrF/CH3Cl adduct was obtained. The preparation from BrF3 and Br2 at 600 °C also delivers BrF in small amounts. The crystal structure of BrCl comes in an ordered and a disordered variety. The
    BrF可以通过使Br 2和F 2在–100°C以下的各种溶剂中反应来制备。在溶液中通过19 F NMR和拉曼光谱法鉴定。从CH 3 Cl溶液中,获得了BrF / CH 3 Cl加合物的单晶结构测定。在600°C下由BrF 3和Br 2制备的溶液也可提供少量BrF。BrCl的晶体结构有序且无序。有序结构是由BR-氯的...Br–Cl链。计算表明,纯净的BrF会以偶极-偶极型聚合物结构结晶,而不是像ClF那样是卤素键合结构。沿着分解路径进入BrF 3和Br 2的可能中间体是Br–BrF 2。

    transition in NBr were obtained from the F Br + HN 3 chemiluminescence flame. The spectra revealed two strong branches, SR and QP, and two much weaker branches, OP and QR, with the QQ branch unobserved. The resolution of the spectrometer was not sufficient to resolve the two naturally occurring isotopes of Br. Analysis of the rotational lines yields the following set of molecular constants: ν00 = 14 812

    Abstract Diode laser spectra of BrF and BrCl below 700 cm −1 were observed and analyzed. Transitions in the 1-0 and 2-1 bands of 79 BrF and 81 BrF and those in the 1-0, 2-1, and 3-2 bands of 79 Br 35 Cl, 81 Br 35 Cl, 79 Br 37 Cl, and 81 Br 37 Cl were fitted to seven and eight Dunham coefficients, respectively. Many BrCl lines, which can be used for wavenumber calibration of diode laser spectra, were

  • Millimeter wave measurements of the rotational spectra of ClF, BrF, BrCl, ICl, and IBr
    作者:Robert E. Willis、William W. Clark
    DOI:10.1063/1.439780
    日期:1980.5
    The rotational spectra of all twelve stable isotopic species of ClF, BrF, BrCl, ICl, and IBr were observed and measured in the millimeter wave region by means of a sensitive microwave spectrometer. Transitions were detected over a wide range of frequencies for molecules in both the ground vibrational state and several excited states. The rotational spectrum of each molecule was split by the nuclear quadrupole interaction. Altogether, 250 new lines were measured. These correspond to 136 pure rotational transitions. Values of the Dunham coefficients Y01, Y11, Y21, Y31, Y02, Y12, and Y03 were obtained from a computer analysis of the measured frequencies. From these coefficients a number of equilibrium constants were derived to significantly greater accuracy than in previous work. In particular, the equilibrium distance, re, was found to two or three more significant figures.
